Application led March 1, 1916. Serial No. :81,328:

To all whom it may concern: v

Be it known that I, JOHN F. OCoNNoR, a citizenotl the United States, residing at they city of Chicago, in the county of Cook and State` of, Illinois, have -invented a certain new` and useful Improvement in Side Bearings for Railway-Cars, of which the following isa full, clear, concise, and exact description, reference being had tothe accom-v panying drawings, forming a part of `this My invention relatesto improveme` side bearings for railway cars.

The object of'my inventionV is to provide a simple and eiiicient side bearing. r

In the drawings formingv a part of this specification, Figure 1 is anend view of my improved side bearing mountedbetween car bclsters,-only part of the holsters being shown in the drawing. Fig. 2 is an enlarged plan view ofthe side bearing. Fig. 3 is a cross section on line 3 3 of Fig; 2.' Fig; l is. a longitudinal `vertical section on line lr-4 Of Fig'. 2.

Referring to the drawings, the numeral 5 its. in

d indicates a body-bolster of a railway car,

(substantially one-half ofthe same being shown in the drawing) and having attached thereto the bearing plate 6. The numeral 7 indicates a` railway car truck-bolster, (substantially one-haltet` same being shown in the drawing) to which is secured my iin-v proved side bearing 8. The side bearing is provided with aroller9 which is adapted ,to engage against the bearingfplate 6, the said roller being of va `general cylindrical shape and provided with the.longitudinal perforation 10 for thel passage of the axle pin 11. The roller may be made of hardiron or other suitable material. The ends ofthe axle'll are received in the perforations 12-12 provided inv the: 1vupright flanges 13e-13 of the cradle 14. The cradle 14 is two Vparts which engage each other at substantially the is substantially circular in cross section, each half of the cradle being provided with a` pon tion of the trunnion that is substantially semi-circular in cross section- Intermediate its ends the bottom of the cradle is inclined Specification of Letters Patent.

inwardly and downwardly, as indicated at the numerals 18-18 in'Fig. 3, forming a 1ongitudinal crown 19l on the under face of the cradle which engages the top face 20 of the bolster 7, the said crown being substantially in the same plane as the lower-face 2.1' of' the cradles trunnions. The two` parts of the cradle may be made, if desired, of malleable iron, though it will be apparent that other suitable materialv may be used. The cradle is held in proper position or-v engaged to the bolster. 7 'by means of the clamp*- plate or'saddle 22 which is provided at either Side with the flanges' 234-23 and ate-ach end with a-stijrrnpQt that is curved about ythe adjacent -.-cradle trunnion. This is clearly illustrated bythe dottedvlines at 25 in Fig. 3 of the drawingsy Thesaddle 22 may: be made of pressed steel or malleable iron `or other suitablev material,and is fastened to the bolster bythe rivets 26 or other similar suitable means. The side bearing is adapted to adjustitself laterally to any changes of theplane of the bearing plate 6 in reference to the plane of the adjacent: face of the roller that may occur in actual operation of cars through the lateral oscillation or tilting' ofthe bearing upon the crown of the cradle `and the trunnions at the ends ofthe ci'adle.-y
